Rosalie Liccardo Pacula is a senior economist at the RAND Corporation and a professor at the Pardee RAND Graduate School. She serves as Director of RAND’s BING Center for Health Economics and is co-director of the RAND’s Drug Policy Research Center. Her research at RAND over the last 15 years has largely focused on issues related to illegal or imperfect markets such as health care, insurance, illicit drugs, and counterfeit goods. Studies and policy analysis measure the size of these imperfect markets, as well as the impact they have on law enforcement and legitimate businesses. Research focuses on demand and supply of illegal substances used for recreational purposes and collateral harms associated with them such as health consequences and crime. She has done extensive work on marijuana markets, including a book published by Cambridge University Press in 2003 entitled “Cannabis Use and Dependence: Public Health and Public Policy”. Currently funded projects evaluate the impact of medical marijuana policies on the consumption of recreational marijuana, modeling prescription drug abuse and treatment in the military, and an examination of barriers to pharmacotherapies for heroin addiction. Pacula has been a member of the National Bureau of Economic Research (NBER) since 1997: Health Economics, the Children Program, and Economics and Crime. She has served as a regular scientific reviewer for the National Institutes of Health, National Science Foundation, and numerous foundations. She is a frequent advisor to the Office of National Drug Control Policy and the European Commission on issues related to substance abuse, addiction, the drug-crime connection, and drug markets. She currently serves on the Coordinating Committee of the International Society for the Study of Drug Policy (ISSDP) and on a standing committee of the American Society for Health Economics (ASHE). She is on the editorial board of the International Journal of Drug Policy and the Journal of Drug Policy Analysis, as well as an Assistant Editor for the international drug journal, Addiction. Pacula received her Ph.D. in economics from Duke University.
